Title: Ubuntu Jammy : A jbd2 process accessing my disk
Post by: Raja Cobra on Oct 10, 2023, 02:03 AM
Hello Guys,
I use a laptop SATA drive to make backups. It is accessed through an SATA/USB interface on my laptop.
I normally create a new file system on this drive and do a dump/restore backup.
     Code:
mkfs.ext4 -m 0  -j -L home  /dev/sde1
mount /dev/sdc1 /mnt
dump 0uaf - /home | (cd /mnt && restore -ruf - )
All run perfect and the dump and restore operations complete in due time. Perfect.
But upon completion, I can't work on the partition (like for an fsck for example) because the disk is busy. And stays busy for a very very long time (hours) with the access light on the interface flashing. (did not wait long enough to see the light stopping flashing)
I've a process accessing the disk :
     Code:
lsof | grep sdc1
lsof: WARNING: can't stat() fuse.gvfsd-fuse file system /run/user/1000/gvfs
      Output information may be incomplete.
lsof: WARNING: can't stat() fuse.portal file system /run/user/1000/doc
      Output information may be incomplete.
jbd2/sdc1 21618                                root  cwd       DIR              253,2       4096          2 /
jbd2/sdc1 21618                                root  rtd       DIR              253,2       4096          2 /
jbd2/sdc1 21618                                root  txt   unknown                                          /proc/21618/exe
So my question is what is going on here and should I worry ?
And are my backup at risk ?
Many thanks in advance for your help and answers.
Have a nice and bright day.
